    Suspension Assuming that this is OEM wheel/tire and there is no any problems with clearance on both sides >>> 100% clear (leaves even more room than OEM)
    Fenders Package will stick out 24 mm (0.9'') farther. Make sure that you have enough room under the fender. If not, consider narrower tires or higher offset.
    Wheelwells Will fill out the wheelwell by extra 20 mm. Make sure that you have enough room under the fender. If not, consider lower profiles or smaller rims.


    this is with a 12 offset will fill 20 more MM of the wheel well. i think i should be good with this size i hope so at least. theres a lot more that goes into this than what i expected i mean my tires now i think are 31.7 over all diameter and 17in wheels so really im only adding about 2 inches with 18 in wheels and 33.4 inch tires so im pretty sure it will all fit
